# AdBlue in the Diesel Tank in Side of the Moor? Keep It Switched Off

AdBlue in your diesel tank? Then leave the engine off — and the ignition too.

In plain terms, AdBlue is simply urea in water.

It does not burn, it does not mix with diesel, and the damage it does begins when your fuel system pulls it in.

A drain and a thorough flush, done where the vehicle is in Side of the Moor, is usually what AdBlue in a diesel tank needs — if it is caught before the engine has run.

Before anything, ring us on 0333 366 0103.

## What to do right now, Side of the Moor: AdBlue in the diesel tank

Do:

- Take the keys out, so no one switches the ignition on.

- Hazards on, if moving traffic is at all close.

- Hold on to the receipt or the empty bottle, and so you can tell us what was put in and roughly how much.

- Ring just where you are. Quote a BL2 4 postcode or the nearest street name, and nobody has to search for you.

Things not to do:

- Shifting the vehicle even a short way is no reason to start the engine.

- Plenty of diesels run their fuel pump the moment your ignition goes on, so keep it off.

- Don't top up with diesel to thin it. AdBlue does not mix in diesel; it separates out.

- Even a short distance along Riding Gate Mews is too far to drive the car.

- Don't try to drain the vehicle yourself by the kerbside.

The attendants on duty at any Side of the Moor filling station — the Morrisons among them — will usually lend a hand pushing it aside if you ask.

On your own drive, don't touch it at all.

## What does AdBlue do in a diesel tank?

The motor isn't what AdBlue is made for; the exhaust is.

From a dedicated reservoir it goes straight to your exhaust, cleaning what the engine emits.

Not one side fits the other: urea doesn't belong in an injection pump, and an injection pump can't take urea.

Fuel blends; AdBlue, after poured in, won't. Its behaviour is not at all like fuel's.

The intake sucks fuel from the deepest part of your tank, and that is just where AdBlue ends up: as it is heavier than diesel, it sinks.

Simplest of all: a vehicle that got AdBlue in Affetside last night and has not been started since. The AdBlue sits at the foot of your tank, undrawn — but it will be first through once the motor starts, before any diesel at all.

Two kinds of harm come from there.

Crystals and corrosion. As the water evaporates, it strands urea that crystallises in filter elements and narrow channels; and, because it eats at certain metals, each part it reaches keeps suffering for as long as it remains inside.

If the AdBlue has reached the pipework, waiting overnight around Side of the Moor makes it worse. Inside your tank only, waiting does nothing.

Diesel protects the high-pressure pump and every injector as it flows; water offers none of that, and that is a separate kind of harm.

## Petrol or AdBlue in a diesel: why AdBlue is frequently worse

A problem of thin fuel is what you get after filling a diesel with petrol from the Shell.

Blended through the diesel and sitting unused, it's no threat for now; running your motor is the harm.

With AdBlue in a diesel, the fluid as such is simply the wrong one.

It doesn't burn, and so it cannot just be run through.

It doesn't stay mixed, so it cannot be weakened. And crystals and corrosion do not wash out with the next tank of fuel. That's why the flush matters more with AdBlue than with petrol, and why starting the motor "to see" costs more here than almost anywhere else, whether the vehicle is in Bottom o th Moor or the middle of Side of the Moor.

As with petrol, there's good news.

Not started? Then the AdBlue sits just in that tank, the simplest section of the entire system to empty, anywhere your vehicle has come to rest around Greater Manchester.

## AdBlue in a diesel tank around Side of the Moor: how it ends up there

It's not on purpose. Plenty of cars keep the AdBlue inlet alongside the diesel one, now and then under one flap, and muddling them up is simple in poor light.

Most of the time it occurs with a bottle bought on the way home and poured in on the driveway, not at the forecourt.

Usually, it occurs in one of a couple of familiar ways.

A warning light comes on during the school run, and the top-up takes place in a hurry outside St Maxentius CofE Primary School.

Close to Seaford Road, a driver pours a bottle in on the drive after work.

Or the vehicle is topped up in the car park outside Grey Mare Inn, in poor light, by someone who has never opened that flap before.

The least familiar vehicles get it the most — hire cars, brand-new ones, fleet cars, and the spare vehicle in a home with both fuel types.

Same mistake, same first step — keep it switched off — wherever you happen to be around Side of the Moor or the remainder of Greater Manchester.

## AdBlue in your diesel tank around Side of the Moor, and the engine started?

Then the AdBlue has left the tank.

Through your filter, through the lines, and — with any running — on to the injection pump and every injector: that is where it has gone.

Lumpy running, smoke from the exhaust, lost power, dashboard lights or cutting out: each might appear, maybe part way across Side of the Moor or returning from Longsight Park.

Stop when it is safe. Switch off. Leave the vehicle off rather than testing it again.

With each start, more of it is pulled through.

Leave the M66, under 5 miles from Side of the Moor, at the first junction and stop somewhere safe, not carrying on.

Distance matters: each mile pushes the AdBlue deeper in, and so heading for Salford, under 10 miles away, makes a much larger job than crossing Side of the Moor to the car park by Longsight Methodist Church Hall.

Approximately how far had it come? Tell us.

There's more to flush once the motor has been started, and our engineers do all of it where the vehicle has ended up.

Noticed early, it very rarely leaves long-term damage.

## Side of the Moor: how AdBlue is drained from a diesel

The vehicle stays where it is, whether that's a road beside Harwood Methodist Church, a driveway, a layby or a filling station around Side of the Moor, and the van comes to it.

Three replies decide the work, and so first our engineers ask what got in, about what quantity, and whether your motor has turned over.

Then that tank is cleared where the car sits, and so the contaminated fuel and the AdBlue come out together.

With AdBlue, more so than with petrol, the flush counts: the fuel system is flushed all the way through because what remains will not flush out unaided.

Testing the vehicle follows at the end, once fresh diesel goes in and the filter gets cleaned or, if necessary, swapped.

If the engine has not run, most jobs take about half an hour once our technicians arrive.

The pumps are explosion-proof, fine on a working forecourt and quiet enough to use outside a house at night.

Last, the fuel system is bled with clean diesel.

You drive off as soon as we have fired it up, and it makes no difference whether your car is on a driveway around Side of the Moor or in a bay at Bromley Cross.

The test before we go is that it runs correctly on new diesel.

The entire job is done where the car is, so it never has to be taken to a workshop.

You get a VAT invoice and an engineer report later on, which is what insurers want.
